In the contemporary era, engineering is generally considered to consist of the major primary branches of chemical engineering, civil engineering, electrical engineering, and mechanical engineering. [ 1] There are numerous other engineering sub-disciplines and interdisciplinary subjects that may or may not be part of these major engineering ...
The main academic full-text databases are open archives or link-resolution services, although others operate under different models such as mirroring or hybrid publishers. Such services typically provide access to full text and full-text search, but also metadata about items for which no full text is available.

The following outline is provided as an overview of and topical guide to engineering: . Engineering is the scientific discipline and profession that applies scientific theories, mathematical methods, and empirical evidence to design, create, and analyze technological solutions cognizant of safety, human factors, physical laws, regulations, practicality, and cost.
Software engineering is an engineering approach to software development. [ 1][ 2][ 3] A practitioner, called a software engineer, applies the engineering design process to develop software. The terms programmer and coder overlap software engineer, but they imply only the construction aspect of typical software engineer workload.
Mechanical engineering is the study of physical machines that may involve force and movement. It is an engineering branch that combines engineering physics and mathematics principles with materials science, to design, analyze, manufacture, and maintain mechanical systems. [ 1] It is one of the oldest and broadest of the engineering branches .
